Scala open back Formal/Prom dress

This dress is BEAUTIFUL. I've only worn it once and its one of a kind. Jeweled high collar with key hole opening in the front, completely teal sequined throughout the whole dress. Open back with a sweeping train. In the last pic you can also see the little button on the back, that holds the dress up so you don't have to! But can be easily taken off as well, it wa aided by the tailor. Fitted for size 2/4
